Title: The Simplicial Volume of Manifolds Fibering over Spheres
Abstract: It is a classical result that manifolds that are total spaces of fiber bundles, whose fiber has amenable fundamental group, have vanishing simplicial volume. In this talk I will explore the opposite question, where the manifolds fiber non-trivially with arbitrary fiber over a manifold with amenable fundamental group. The main focus will lay on manifolds fibering over spheres and an application to characteristic classes. All of this is joint work with Jens Reinhold.
